Common Problems and Solutions for Ceramic Raw Material Grinding Mill Maintenance

Ceramic raw material grinding mills are essential equipment in the production of high-quality ceramic products. However, like any industrial machinery, they are prone to various operational issues that can affect performance and productivity. This article explores common maintenance challenges and provides practical solutions, while highlighting ZENITH’s advanced grinding solutions.

1. Excessive Vibration

Problem: Abnormal vibration during operation often indicates mechanical imbalance or bearing wear.

Solutions:

  • Regularly check and replace worn bearings
  • Ensure proper alignment of rotating components
  • Balance grinding rollers and classifier rotors

2. Reduced Grinding Efficiency

Problem: Gradual decline in output capacity or inconsistent fineness.

Solutions:

  • Inspect and replace worn grinding elements (rollers, rings)
  • Adjust classifier speed for optimal particle distribution
  • Monitor feed consistency and moisture content

For operations requiring ultra-fine grinding up to 2500 mesh (5μm), ZENITH’s XZM Ultrafine Mill offers exceptional performance with its high-precision vertical turbine classifier and energy-efficient design, achieving 30% lower power consumption compared to conventional mills.

3. Bearing Overheating

Problem: Abnormal temperature rise in bearing assemblies.

Solutions:

  • Maintain proper lubrication with recommended grease
  • Check for contamination in lubricants
  • Ensure adequate cooling airflow

4. Excessive Wear of Grinding Components

Problem: Premature wear of rollers, rings, or liners.

Solutions:

  • Use high-chrome or ceramic composite wear parts
  • Implement proper material feed control
  • Consider ZENITH’s MTW Series Trapezium Mill with its patented anti-wear shovel design that extends component life by 30%

5. Dust Leakage

Problem: Environmental contamination from escaping powder.

Solutions:

  • Inspect and maintain sealing systems
  • Ensure proper operation of pulse dust collectors
  • Maintain negative pressure in grinding chamber

6. Motor Overload

Problem: Frequent tripping of motor protection devices.

Solutions:

  • Check for material overloading
  • Inspect electrical connections
  • Verify proper voltage supply

Preventive Maintenance Best Practices

Implementing a comprehensive maintenance program can significantly extend equipment life:

  1. Daily visual inspections of critical components
  2. Weekly lubrication of moving parts
  3. Monthly vibration analysis
  4. Quarterly complete system inspection
  5. Annual major overhaul
